BUTTER-SH SPECIFICATION forming part of Letters Patent No. 305,990, dated September 30, 1884.

Application filed April 1, 1884. (No model.)

To a/ZZ whom, it may concern:

Beit known that I, CHAELEs YAENALL, Jr. ,a citizen of the United States, residing at Philadelphia, in the county ot' Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Butter-Shipping Boxes, of which the following is aspecification.

The nature of my invention will be understood by the following description, in connection with the claims appended thereto.

In the accompanying drawings, which make a part of this specification, Figure l is a plan view of a butter-shipping box, with my iniproveinent attached, with the outer lid oft". Fig. 2 is a rear elevation of the saine. Fig. 3 is a top or plan view of a rear corner-iron, having a projection, d, provided with a slot, e. Fig. 4 is an end elevation of the same. Fig. 5 is a vertical section at the broken line .r .r of Fig. (i. Fig. 6 is a top view of the box.

Like letters of reference in all lthe gures indicate the same parts.

A represents a butter-shipping box having my improved corner-irons B connected therewith. One ot' the irons is shown in detail in Figs. and 1. These irons consist of the ordinary cornenplate, a, and the additional horizontal plate Z), cast in a single piece, as shown in Figs. 3 and Li, which binds the corner in the usual manner when connected with a box, as shown in Figs. l and 2. The part b is sunk in the edges of the end and side of the box, binding the latter together, when it is held in place by means ofscrews c. (Shown in Fig. l.) I usually construct the said irons of malleable iron, but do not confine myself to the use of that material, as other materials will answer the purpose. It will readily be seen that the additional plates b, being coniined by Ineans of screws which are at right angles to the coniiningscrews ot' the parts c, give great additional strength to the corners of the chest, especially as their binding-screws c are at right angles to the screws c of the plates c. The

plates b at the rear corners have projections d, provided with slots e, for the reception of sliphin gesf. These projections have heretofore been used, however, lwith a single straight plate, and are only new when combined with 5o my flat L-shaped plates.

C is the lid of the box A, which is connected therewith by means of the slip-hingesff and plates b b, having slots e, described above, the cover being confined at the front by the well- 55 known device consisting of the hasp g and staple 71..

C is an inside cover of the box, made in two pieces, and' connected together by means of hinges D D, as shown in Fig. l. The objeot'o of having it in two pieces is to give facility to uncover only a part of the butter when it is unnecessary to expose the whole surface.`

A series of trays, E, are shown in Fig. 5, the corners of which set in the rabbets i) c' c' i of 65 the corner-posts H H H H, as seen in said gure. The inside cover, G, rests upon the upper tray. These trays are set inside the posts, as shown', for the purpose of leaving a space around them between theln and the vertical 7c inside surfaces of the box, for `the circulation of cold air, and also for convenience in taking hold of' the trays in removing them from or placing them in the box. The space G, centrally arranged in the box, is for the purpose 7 5 of containing ice to keep the butter cool, the access to said space being made by turning over the hinged covers C.

I make no claim to the inside cover, C', except constructing it in two pieces for the ac- So complishment of the 'object stated, as it has been made heretofore -in a single piece to proteot the butter when the lid is thrown up; nor do I claim any other inside construction of the box, as the parts shown are well known in but- 85 ter-boxes, and are only shown here as an illustration of the use ofthe box; but l I claim as my invention- In a casting having corner-plates a and hori zontal plates b cast-in a single piece, the pro- 9o jection d, provided with slots c, substantially as described.
